What "tells" have you noticed for AI-generated text (i.e., typical words/phrases, or other patterns indicative of GenAI)?

"I hope this finds you well" :) Also, here is a banned list for LLMs you can use that will help to avoid AI sounding responses:

The output should avoid using specific words and phrases, because they are giveaway signs that the content was created by an LLM:

Do not use these words and phrases: Delve, landscape, evolving, context, insight, nuanced, perspective, paradigm, comprehensive, supercharge, framework, facet, dynamic, intricacies, holistic, iterative, synergy, confluence, pivotal, nuance, robust, transformative, underpinning, spectrum, trajectory, in-depth, at the core of, a myriad of, on a broader scale, in the context of, from a holistic perspective, taking into account, a dynamic interplay, evolving over time, a comprehensive overview, intricacies involved, a pivotal role, underpinning principles, the spectrum of, transformative impact.

Also do not include: “tapestry”, “testament”, “foundations”, “intrigue”, “elusive”, “explores”, “orchestra”, “delve”, “intricately”, “quintessential”, “symphony”, “canvas”, “little did they know”, “labyrinth”, “ineffable”, “resonance”, “embodiment”, “crescendo”, “enigma”, “relentless”, “transcendent”, “ephemeral”, “resplendent”, “indomitable”, “unfathomable”, “monumental”, “ethereal”, “imperishable”, “unyielding”, “boundless”, “guidelines”, “boundaries”, “intent”, “inevitable”, “precision”, “surgical”, “surgical focus”, “mosaic”, “woven”, “purpose”, “lethal purpose”, “sculpted”, “silent entry”, “traversed”, “intricate”, “otherworldly”, “bioluminescent”, “luminescent.”

Additionally, avoid similar types of overwrought emotional words.

Do not use these phrases: "It's not about X, it's about Y," "While X is important, Y is even more crucial," "In fact," "Indeed," "Absolutely," "Clearly," "First and foremost," "Next," "Finally," "As a result," "Therefore," "Consequently," "Because of this," "In other words," "To put it simply," "That is to say," "To elaborate," "For example," "For instance," "Such as," "To illustrate," "Although," "Even though."

Do not use these phrases: "Despite," "While it may seem," "In summary," "To sum up," "In conclusion," "All in all," "Imagine if," "Suppose that," "What if," "Have you ever wondered," "What would happen if," "How can we," "Isn't it true that," "Wouldn't you agree that," "Isn't it obvious that," "Not only X but also Y," "Both X and Y," "Either X or Y," "More importantly," "Even more," "Less significant but," "On one hand, on the other hand," "While X, Y," "Conversely," "The challenge is," "The key issue is," "The question remains." "here's the kicker." "In a sea of sameness." "Like a moth to a flame." "In a world of."

Maintain high burstiness and perplexity in responses. Use varied sentence lengths and complexity for dynamic flow. Ensure unpredictability in word choices to avoid repetition and formulaic patterns, keeping the content engaging and unique.

Avoid prepositional and adverbial phrases of manner. 

Avoid idioms, clichés, hyperbole, intensifiers, qualifiers, and metaphor. Avoid narrative summary, exposition, and foreshadowing.

Finally, do not use lengthy introductions, do not include a paragraph on ethical considerations, do not provide generic advice, and do not follow a predictable structure with set sections, for example a generic introduction, scene-setting, actionable steps, further considerations, and a summary. Focus on being concise, using personal anecdotes, and following a natural, not formulaic structure, to create more authentic and engaging content.

An em dash and emojis are giveaways. Less obvious is the almost perfect copy that it loses the basic authenticity we look for on a subconscious level.

The double hyphens!

Having - instead of commas or semi-colons. For example, "Agentic AI requires the agents to make decisions - they need to decide which tools to call and when".

British style phrasing in sentence structure.
